My FX Maverick has an orca digital gauge on it. I’ve noticed an interesting trend now that I can see the pressure down to the exact bar. When going out into the colder weather this time of year the pressure actually creeps up by 4-5 bar. This is opposite of what I thought would happen but I’m thinking that maybe the reg interacting with the cooler less dense air?? For example, my 2nd reg runs 105 bar approx in the warm house. If I take it outside it will end up at 108-109. It will stay there inside the house even when warmed up. However, if I fire three or for dry fires after warm the reg settles right back to 105 and stays there . Anyone else notice this or can explain it?
